bisexuality-and-sexual-orientation

In this chapter, the characters discuss the social and biological differences between Neanderthals and modern humans, focusing on sexuality, reproductive behavior, and social organization. Ponter explains the Neanderthal practice of synchronized menstruation and controlled mating periods ('Two become One'), contrasting it with human hidden ovulation and diverse sexual orientations. The conversation also touches on the evolutionary reasons behind male retreat during certain menstrual phases and critiques human assumptions about sexuality and gender roles.
